Meet prototype PETMAN,
"an anthropomorphic robot for testing chemical protection clothing used
by the US Army" and supposedly "the first anthropomorphic robot that
moves dynamically like a real person." Thanks to uncanny balance and
bipedal motion, PETMAN is designed to stress-test military battle suits
by simulating the rigors of combat -- and perhaps even "human
physiology within the protective suit by controlling temperature,
humidity and sweating."

Guys, when we start making robots that can break into a sweat, it's pretty much Singularity time.
